The Sigma 30mm f/1.4 EX
DC HSM is a large aperture lens that provides a standard angle most similar
to the human eye. The 30mm focal length translates to approximately 50mm in 35mm
format(*).

A glass mold aspherical lens element
at the rear group of the lens reduces color aberration and provides high-quality
image results. From 15.7" (40 cm) minimum focusing distance to infinity, this lens
creates very sharp images with high contrast, and can perform superbly in a great
range of applications, including snapshots, portraiture, indoor shooting and landscape
photography.

DC lenses are exclusively designed
for digital SLR cameras. The image circle (rear of lens) is made to match the smaller
dimensions used for the image sensor on digital cameras. As a result these lenses
are also more compact and lightweight, and are better matched to digital SLR cameras.

Note: (*) Not suitable for 35mm
film SLR cameras or for any digital SLR camera with image sensor bigger than APS-C
size, e.g. 1D series or Kodak Pro SLR/c.

EX lens series denotes excellence of engineering and new technology

Correction for various types of aberration provided by two SLD (Special
Low Dispersion) glass element and a hybrid aspherical lenses
